  1. I have already checked for codes and it gave me #55 (no malfunction). Its a new tbi unit so Im assuming the whistling is because I cleaned the EGR port and the pipe on the mixture pre-heater is making it whistle. Ita at a shop (that I work at) and Ive gotten it to run. However, it is extremely rough. The surging has gone done quote a lot, it idle and runs, but is very, vey rough. I replaced the 2 injectors and we tried messing with some vacuum lines but its stop really rough. Maybe ignition timing?
  2. And the whistling noise is coking from inside / underneath the throttle body. However I have just swapped tbi units and its still whistling so its not a gasket. Im thinking the mixture heater pipe is causing the EGR tube to make a whistling noise
  3. Im pretty sure it isnt timing because itll run for just a few seconds then ill choke itself out while it sputters to a stop. My timing belt was serviced before I bought this truck but the sticker has been wiped clean so I cant see the mileage anymore.
  4. What happened, did you get it fixed? Im having a similar problem
  5. I have an '88 Pathfinder 3.0 v6 that has been giving me trouble for the past 5 months. I just replaced the throttle body (entire unit, sensors too) and now I have a whole new problem. It used to surge up and down erratically, but now it wont even stay running. I think its flooding itself out. It also has a high pitched whistle (no, I dont have a vacuum leak. Ive checked) and will run fine for a few seconds then stumble and die. Ive been struggling for months with this problem, can someone please help me?
  6. Tried searching for a vacuum leak but nothing worked. Sprayed everywhere with starting fluid and nothing happened. Gonna replace the tbi unit
  7. How did cleaning your tbi go? Did it start working again or give you any problems? I rebuilt mine and now its wheezing and whistling and revving up and down
  8. Thanks, Ill give it a try. Anything else I could test while Im at it? Im pretty close to just buying a new Throttle Body unit
  9. Well, it does have suction, but I can put my hand over it and it doesnt change anything. I have tirelessly searched this and other forums for a problem like mine and havent found an answer. Im close to just sending it somewhere to get fixed
  10. I searched for vacuum leaks and couldn't find anything. Sprayed every hose on both ends and the engine didnt react. After a few minutes amd a couple starts I ended up vapor-locking it and gave up. Got any other ideas?
  11. I cant hear it making any sucking noise, because its whistling too loud. Ive got a new can of ether so tomorrow night Ill give it a shot. Any ideas where to start? Likely areas?
  12. I have checked my computer and got a code 55 (no malfunction) I could take the throttlebody off and try the throttle plate screws. It didnt close all the way when I had it off replacing the gaskets. However, there it literally no suction coming from the throttlebody. Im going to test for vacuum leaks tonight
  13. I've replaced my gaskets and made sure everything worked and I still have the revving up and down problem. (Approximately 2,000-2500) Can anyone help me? I have no codes but am pretty sure its a vacuum leak. I just don't know where
  14. My 1988 Pathfinder VG30i gave me a 55 (no malfunction) today, however there is a vacuum leak that might be causing the idle do rev up and down (approximately 1700-2500). I chased it down to behind the throttle body. Should I take it off and try to tighten it down again or look for something else?
